When using a detector which has been well ground balanced, and by using the Th Level
setting at 0 a sound signal will be received from a metal object. The only way of identifying an
object is by checking the information shown on the display.
The key characteristic of this
mode is that it provides the maximum detection range for all metal objects in the ground.
NOTE: In this operating mode it is important to reset the All metal channel, this needs to be
done away from metal objects. For best operation in Non-motion mode, listen to the Threshold,
this should be set so that it can be heard. If the Threshold becomes inaudible then a reset is
required, equally if the detector suddenly starts creating a loud sound with no apparent reason,
then reset the channel.
NOTE: In the Non-Motion mode the object ID information is sent from the Motion channel so
that the search coil motion is required for the information to appear on the screen.
All metal Motion
A mode of work which enables searching for large objects but with the ability to
separately identifying many small objects in the ground. This is All metal mode, where
movement of the search coil is required. Works with SAT setting above 0.
The detector uses sound to signal all metal objects. When the search coil is stopped in
close proximity to a metal object, the detector will automatically „tune” itself to the metal and
stop signaling the object. How long this takes will depend on the SAT value: if SAT is set to 1
then this will be 1 second, if SAT is set to 20 – it will be approximately 0.7 seconds.
Under certain conditions, and depending on the ground balance, the detector may react
to non-metallic objects. Hot rocks and other objects which have properties which are not similar
to soil, may create a sound signal. An experienced user will have no problem differentiating
these signals from normal signals as they have very different characteristics. The only way to
identify the conductivity of these metals is to check the ID readouts on the display. The All metal
Motion mode has greater range than the Motion mode with discrimination.
NOTE: When listening to deeply placed objects it is a common mistake to swing the search coil
too quickly over an object. After the search coil passes over an object and emits a sound, the
Threshold will be turned down. To confirm an object has been located it is important to wait for
the Threshold to return to its original level. This time can be shortened by resetting the All metal
channel using the trigger.
3. Dual mode
This mode combines the Motion mode with discrimination and the All metal mode. This
combination provides the advantages of both modes – identification coming from the Motion
channel and the maximum range of the All metal channel. To better understand the
characteristics of the Dual mode it is best to get to know the following modes first: Motion with
discrimination and All metal Non-motion with different speeds.
